Referring to Figure 1, Figure 1 is a schematic diagram of a network structure applicable to some embodiments of the present invention. ) Or other terminal devices, such as: mobile phones, tablet computers (Tablet Personal Computer), laptop computers (Laptop Computer), personal digital assistants (PDA), mobile Internet devices (Mobile Internet Device, MID) or Terminal-side devices such as wearable devices (Wearable Device), it should be noted that in this publication In some embodiments, the specific type of terminal is not limited. The network side equipment 12 may be a base station, such as a large station, LTE eNB, 5G NR NB, etc.; the network side equipment may also be a small station, such as a low power node (LPN, low power node), pico, femto, etc. Or the network side equipment can be an access point (AP, access point); the base station can also be a network composed of a central unit (CU, central unit) and multiple transmission reception points (TRP, Transmission Reception Points) managed and controlled by it. Road node. It should be noted that, in some embodiments of the present invention, the specific type of the network side device is not limited.

Please refer to Figure 2. Figure 2 is a flowchart of a DCI transmission method provided by some embodiments of the present invention. As shown in Figure 2, it includes the following steps: Step 201: The terminal receives the first DCI sent by the network side device, The first DCI includes first indication information. The first indication information is used to indicate that the terminal does not perform PDCCH monitoring (PDCCH monitoring) for subsequent N detection opportunities, or is used to indicate that PDCCH detection is to be performed at the next detection opportunity, or is used to indicate at least Stop PDCCH detection in the current DRX on period, and the N is an integer greater than or equal to 1; Step 202: If the first DCI is successfully decoded, the terminal responds to the first indication information.

Wherein, the above-mentioned first indication information may be a bit field in the first DCI, and the above three states are indicated by the bit value of the bit field.

The foregoing not performing PDCCH detection on subsequent N detection opportunities may be skipping (skip) N detection opportunities to perform PDCCH detection. For example, if the current detection opportunity of the first DCI is detected as the detection opportunity n, when the above N is 3, the detection opportunity n+1, the detection opportunity n+2, and the detection opportunity n+3 are skipped.

And the PDCCH detection at the next detection opportunity mentioned above can be The PDCCH detection is continued at the next detection opportunity of the current detection opportunity of the first DCI.

The foregoing stopping PDCCH detection at least in the current DRX on period may be: stopping the PDCCH detection after detecting the foregoing first DCI, that is, stopping the PDCCH in at least the current DRX on period. In addition, stopping PDCCH detection at least within the current DRX on period can also be referred to as stopping PDCCH detection and entering a sleep state.

The response to the first indication information may include: skipping the N detection opportunities when the first indication information is used to instruct the terminal not to perform PDCCH detection on the subsequent N detection opportunities; or using the first indication information In the case of instructing to perform PDCCH detection at the next detection opportunity, PDCCH detection is performed at the next detection opportunity; or the above-mentioned first indication information is used to indicate that PDCCH detection and PDCCH detection should be stopped at least within the current DRX on period.

In addition, it should be noted that in some embodiments of the present invention, the above-mentioned detection opportunity is for the terminal, and for the network side device, the above-mentioned detection opportunity can be called a transmission opportunity, that is, the detection opportunity of the present invention In some embodiments, the detection opportunity and the transmission opportunity are the same opportunity.

In some embodiments of the present invention, through the above-mentioned first DCI, the flexibility of PDCCH detection of the terminal can be improved, and the power consumption of the terminal can be reduced.

As an optional implementation manner, the first indication information includes a detection status field (PDCCH monitoring status field); wherein, the detection status field is used to indicate one of three states, and the three states include: incorrect subsequent N detection opportunities for the first state of PDCCH detection, in the next detection opportunity The second state of PDCCH detection and the third state of stopping PDCCH detection at least within the current DRX on period; or the detection state field is used to indicate one of the two states, the two states include: incorrect subsequent N The first state of PDCCH detection at the detection opportunity and the second state of PDCCH detection at the next detection opportunity.

In this embodiment, it can be realized that the detection status field includes the first state, the second state, and the third state. For example, 01 indicates the first state, 10 indicates the second state, and 11 indicates the first state. Three states. In this way, the indication of these three states is realized through a bit field, so as to save the overhead of DCI.

In addition, in this embodiment, it can also be realized that the detection status field includes the two states of the first state and the second state.

Optionally, the detection status field may have a special state, for example: the detection status field is a special value (for example: 00), which means invalid, or no indication is given. For example: when the above first indication information is used to indicate that PDCCH detection should be stopped at least within the current DRX on period, and the detection status field includes only two states, the detection status field can be set to a special value. For example: 00, or the detection status field is not included in the first DCI.

As an optional implementation manner, the above-mentioned first indication information includes an indication field included in the first DCI, and the indication field is used to instruct to stop PDCCH detection at least in the current DRX on period.

It should be noted that the above indication field is used to indicate to stop PDCCH detection at least within the current DRX on period. When the above indication field has a specific value, the indication field indicates to PDCCH detection is rarely stopped in the current DRX on period, that is, the above indication field can be used to indicate whether to stop PDCCH detection at least in the current DRX on period. For example: in the case where the first indication information includes the detection status field, and the detection status field indicates the first state or the second state, the indication field does not indicate to stop at least within the current DRX on cycle PDCCH detection. That is, the first DCI may include at least one of the detection status field and the indication field.

As an optional implementation manner, when the first indication information is used to indicate that PDCCH detection is stopped at least within the current DRX on period, the first DCI and PDSCH are not transmitted in the same TTI, or the indication information is used Instructing to stop PDCCH detection at least in the current DRX on period, the first DCI and the non-physical layer signaling used to instruct to stop PDCCH detection at least in the current DRX on period are transmitted in the same TTI, or the first DCI and The non-physical layer signaling is not transmitted in the same TTI.

Wherein, the above-mentioned TTI may be a certain time domain resource, such as: sub-frame, time slot (slot) or mini-slot (mini-slot), etc.

The aforementioned PDSCH may include a Media Access Control Control Element (MAC CE) or other PDSCH signals.

Since the first DCI and PDSCH are not transmitted in the same TTI, the first DCI can be referred to as a PDCCH trigger signal used to trigger the terminal to stop PDCCH detection (PDCCH trigger), which is used to trigger the terminal at least in the current DRX on cycle Stop PDCCH detection internally, for example: enter the sleep state.

And in this embodiment, since the first DCI and PDSCH are not the same Transmission within TTI. In this way, the PDCCH is decoded correctly and the PDSCH is decoded incorrectly. The terminal will no longer perform subsequent PDCCH detection, but can receive the retransmitted version of the PDSCH in error to avoid packet delay to the next DRX cycle Send to ensure the delay performance of the terminal. In the same way, the foregoing first DCI and the non-physical layer signaling are not transmitted in the same TTI, and the same beneficial effects can also be achieved.

The aforementioned non-physical layer signaling that stops PDCCH detection at least in the current DRX on cycle may be signaling other than physical signaling, and is used to instruct to stop PDCCH detection at least in the current DRX on cycle, for example: Instruct the UE to stop the MAC CE of the inactive timer in the DRX on period.

In addition, in the foregoing embodiment, since the first DCI and non-physical layer signaling can be transmitted in the same TTI, the PDCCH is decoded correctly but the PDSCH is decoded incorrectly, and the terminal does not perform subsequent PDCCH detection to avoid non-physical layer signaling. Delay the transmission to the next DRX cycle to ensure the delay performance of the terminal. For example: if the first DCI decodes successfully, the terminal responds to the first indication information, which may include: if the first DCI decodes successfully, the terminal returns the ACK corresponding to the non-physical layer signaling to the network side device, And according to the first DCI, PDCCH detection is stopped at least within the current DRX on period.

It should be noted that, in the embodiment, since the above-mentioned first indication information is used to indicate that PDCCH detection should be stopped at least within the current DRX on period, regardless of whether the above-mentioned non-physical layer signaling is successfully decoded, the corresponding non-physical layer signaling is returned ACK, that is, the HARQ-ACK corresponding to the non-physical layer signaling is set as an ACK and fed back to the network side device, so that the network side device does not send PDCCH to the terminal at least during the current DRX on period, and stops sending the non-physical layer signaling . And since the decoding is successful only in the first DCI, the non-physical layer signaling pair is fed back to the network side device Corresponding ACK can also save transmission resources.

Optionally, in the foregoing embodiment, the terminal responding to the first indication information includes: if the first DCI is successfully decoded, and the effective time of the first DCI is earlier than the effective time of the non-physical layer signaling, according to the first DCI A DCI stops PDCCH detection at least within the current DRX on period.

In this implementation manner, if the effective time of the first DCI is earlier than the effective time of the non-physical layer signaling, PDCCH detection is stopped at least within the current DRX on period according to the first DCI.

Specifically, the time for stopping PDCCH detection is the minimum value of the effective time of the first DCI and the effective time of the non-physical layer signaling. For example: the first DCI instructing the terminal to no longer perform PDCCH detection and the MAC CE used to instruct the terminal to stop the inactive timer in the DRX on period are transmitted in the same TTI, and the time to stop PDCCH detection is taken as this The minimum value for the two signaling to take effect.

Optionally, in the foregoing embodiment, the method further includes: when the first DCI and the non-physical layer signaling are not transmitted in the same TTI, and the first DCI is not successfully decoded, the non-physical layer signaling is not successfully decoded In this case, if the terminal returns a NACK corresponding to the non-physical layer signaling to the network-side device, the terminal receives the second DCI sent by the network-side device, and the second DCI includes second indication information. Used to indicate that the terminal does not perform PDCCH detection on subsequent M detection opportunities, or to indicate PDCCH detection at the next detection opportunity, or to indicate to stop PDCCH detection at least in the current DRX on period, the M is greater than or equal to 1. Integer.

Wherein, the unsuccessful decoding of the first DCI may be a packet loss or a decoding error, The unsuccessful decoding of the aforementioned non-physical layer signaling may be a decoding error or packet loss.

In this embodiment, if the first DCI is not successfully decoded and the non-physical layer signaling is not successfully decoded, if the terminal returns a NACK corresponding to the non-physical layer signaling to the network side device, the network side device will send the first Two DCI, so as to avoid the situation that the terminal cannot skip the detection opportunity, continue to detect the next detection opportunity, or stop the PDCCH detection, so as to save the power consumption of the terminal.

It should be noted that the foregoing second DCI and the foregoing first DCI may be the same or different, and the foregoing M may be less than or equal to the foregoing N. In addition, the second DCI sent by the network side device may be sent in the same TTI as the non-physical layer signaling, or sent in a different TTI.

As an optional implementation manner, the method further includes: if the first DCI is not successfully decoded, the terminal receives a third DCI sent by the network side device, the third DCI includes third indication information, and the third indication Information is used to indicate that the terminal does not perform PDCCH detection for subsequent W detection opportunities, or to indicate PDCCH detection at the next detection opportunity, or to indicate to stop PDCCH detection at least during the current DRX on period, and W is greater than or equal to 1. Integer.

It should be noted that if the first DCI is not successfully decoded, the terminal may receive the third DCI sent by the network side device. The first DCI may not be decoded successfully, and the terminal does not return HARQ-ACK (ie, ACK and NACK is not returned), the network side device does not detect the HARQ-ACK, and thus sends the third DCI. For example, the above PDCCH decoding fails (or called a decoding error), resulting in packet loss. In addition, the aforementioned HARQ-ACK may be HARQ-ACK corresponding to PDSCH.

The first indication information in the above-mentioned first DCI may indicate the three conditions in step 201. Any state in the state. Optionally, to instruct the terminal not to perform PDCCH detection for N subsequent detection opportunities, or to instruct to stop PDCCH detection at least within the current DRX on period.

The foregoing third DCI and the foregoing first DCI may be the same or different, and the foregoing W may be less than or equal to the foregoing N. In addition, the third DCI sent by the network side device may be sent in the same TTI as the non-physical layer signaling, or sent in a different TTI.

In this embodiment, since the network side device does not detect the HARQ-ACK, the network side device sends the third DCI to the terminal, so as to avoid the situation that the terminal cannot skip the detection opportunity, continue to detect the next detection opportunity, or stop PDCCH detection , In order to save the power consumption of the terminal.

Optionally, in this embodiment, the receiving time of the third DCI is before the end position of the N detection opportunities indicated by the first DCI; or the receiving time of the third DCI is within the current DRX on period.

For example: when the first indication information is used to indicate PDCCH detection for N subsequent detection opportunities, the terminal receives the third DCI before the end position of the N detection opportunities; for another example: When instructing to stop PDCCH detection at least in the current DRX on period, the terminal receives the third DCI in the current DRX on period.

Optionally, the first DCI is used to indicate that the terminal does not perform PDCCH detection for subsequent N detection opportunities, or the first DCI is used to indicate that PDCCH detection is stopped at least within the current DRX on period, and the first DCI and PDSCH In the case of transmission in the same TTI, if the terminal successfully decodes the first DCI but fails to decode the PDSCH, it can return the NACK corresponding to the PDSCH to the network side device, and the network side device detects the NACK corresponding to the PDSCH , You can stop the terminal's downlink transmission to save transmission resources. Wherein, stopping the downlink transmission of the terminal may be stopping PDCCH transmission, or stopping PDCCH and PDSCH transmission. lose.

Optionally, when the N is a static or semi-static configuration of the network side device, the terminal may obtain a specific value corresponding to the N in advance, and the first indication information is also used to indicate that the value of N is the Specific value.

The foregoing specific value may be configured by the network side device for the foregoing terminal through RRC signaling, MAC CE, or other signaling.

The above-mentioned first indication information may indicate the value of the above-mentioned N by 1 bit to indicate the specific value, so that it is possible to indicate the value of the above-mentioned N by 1 bit. For example: 1 bit (for example: 1) in the detection status field can indicate the number of detection opportunities that the terminal needs to skip. It can be seen that this embodiment can save the overhead of the first DCI.

Optionally, when the N is a dynamic configuration of the network side device, the terminal obtains a plurality of candidate values corresponding to the N in advance, and the first indication information is further used to indicate that the value of the N is the plurality of candidate values. One of the candidate values; or when the N is a dynamic configuration of the network-side device, the terminal obtains multiple candidate values corresponding to the N in advance, and the terminal receives the fourth instruction information sent by the network-side device, The fourth indication information is used to indicate the target candidate value among the plurality of candidate values, and the first indication information is also used to indicate that the value of N is the target candidate value.

Wherein, the above multiple candidate values are configured by the network side device for the above terminal through RRC signaling, MAC CE or other signaling. For example: N configures multiple candidate values, such as N={2, 5,10,15 20,25,40,80}. In one implementation manner, the value of N may be directly indicated in the first indication information to achieve dynamic configuration; in another implementation manner, the target candidate value may also be indicated through the fourth indication information, for example: The network side device can dynamically notify the terminal through MAC CE, the index of the specific configuration value of N, that is, the index indicating the above-mentioned target candidate value, and the terminal is indicated by 1 bit (for example: 1) in the detection status field The value is the target candidate value, that is, the value of the indication N is the candidate value indicated by the fourth indication information. In this way, one bit (for example: 1) in the detection status field can be used to instruct the terminal to obtain the number of slots that need to be skipped.

It should be noted that the fourth indication information may be sent before the first DCI, or may be sent at the same time, which is not limited.

It should be noted that both M and W in some embodiments of the present invention can be configured in the manner of configuring N described above.

Therefore, the terminal PDCCH detection flexibility can be improved through the above-mentioned first DCI, and further The power consumption of the terminal can also be saved.

The following several embodiments are used to illustrate the methods provided by some embodiments of the present invention. It should be noted that the following transmission opportunities and detection opportunities can be understood as the same opportunity.

Embodiment 1: A PDCCH monitoring status field is carried in the DCI, that is, a PDCCH detection status field. Preferably, the field can be composed of multiple consecutive bits. The field has three states corresponding to the following three function indications: terminal Do not perform PDCCH detection on subsequent N transmission opportunities, where N is statically, semi-statically or dynamically configured by the network side device; continue to perform PDCCH detection at the next transmission opportunity; stop PDCCH detection and enter the sleep state.

A specific example is shown in Figure 4. The PDCCH detection status field can be indicated by two bits. When the field value is [0 1], the terminal will skip the PDCCH detection opportunities of N slots, and the value of N is the network. The roadside equipment is semi-statically or dynamically instructed by the terminal through RRC signaling or MAC CE. The best and simplest way is for the network side equipment to semi-statically configure the specific value of N for the network side equipment through RRC signaling, and the PDCCH detection status field One bit of 1 can be used to indicate the number of transmission opportunities that the terminal needs to skip. The method is the simplest but requires the value of N to be fixed within a certain period of time, and the flexibility is not high. Another method is that the network side equipment configures multiple candidate values for N through pre-appointment, namely static mode, or RRC signaling configuration, namely semi-static mode, such as N={2,5,10,15 20,25,40,80} , The network side device can dynamically notify the terminal through MAC CE, the index of the specific configuration value of N, then only one bit 1 is needed in the PDCCH detection status field to enable the terminal to obtain the number of slots that need skip. Wherein, the information of N can be indicated in advance before the terminal adopts it, otherwise, a preset value of N can be predefined.

As shown in Figure 4, after the terminal skips the PDCCH detection of N transmission opportunities, it detects the PDCCH at the new PDCCH transmission time and detects the signaling [0 0] from the PDCCH detection status field of the DCI. A transmission opportunity continues to detect the PDCCH; when the terminal detects signaling [1 1] in the PDCCH detection status field, it will no longer detect the PDCCH on the subsequent slot or PDCCH detection opportunity in the DRX ON period. It should be pointed out that the number of bits contained in the PDCCH detection status field and its representation method are just examples. For example, the value of N can be configured using RRC signaling to configure the set of candidates for N (candidates), but MAC CE is not used to notify the terminal. Then, the candidates index is carried by the PDCCH detection status field of the DCI. At this time, the number of indicator bits used will increase significantly.

As mentioned above, when using the DCI at the current moment to instruct the terminal to skip the PDCCH detection opportunities of N slots, if the DCI decoding is wrong, the terminal cannot stop the PDCCH detection, and the network side device side can be: the terminal will skip when receiving the instruction Before the HARQ-ACK corresponding to the PDSCH scheduled by the DCI with a PDCCH detection opportunity of N slots, the network side device stops scheduling the terminal for downlink transmission.

If the network side device cannot detect the HARQ-ACK, the network side device can resume scheduling downlink transmission at the next PDCCH transmission opportunity. If the HARQ-ACK is an ACK, the network side device needs N PDCCH transmission opportunities not to perform downlink data scheduling.

Embodiment 2: A PDCCH monitoring status field is carried in the DCI, that is, a PDCCH detection status field. Preferably, the field is composed of several or more consecutive bits. The field has two states corresponding to the following two functions respectively Instructions: The terminal does not perform PDCCH detection for the subsequent N transmission opportunities, where N is statically, semi-statically or dynamically configured by the network side equipment; continue to perform at the next transmission opportunity PDCCH detection.

A specific example is shown in Figure 5. The PDCCH detection status field can be indicated by 1 bit. When the field value is [1], the terminal will skip the PDCCH detection opportunities for N slots, and the N value is the network side The device semi-statically or dynamically instructs the terminal through RRC signaling or MAC CE. The best and simplest way is for the network-side equipment to semi-statically configure the specific value of N for the network-side equipment through RRC signaling, in the PDCCH detection status field One bit 1 can realize the indication of the number of transmission opportunities that the terminal needs to skip; the method is the simplest but requires the value of N to be fixed within a certain period of time, which is not very flexible. Another method is that the network side equipment configures multiple candidate values for N through pre-appointment, namely static mode, or RRC signaling configuration, namely semi-static mode, such as N={2,5,10,15 20,25,40,80} , The network side device can dynamically notify the terminal through MAC CE, the index of the specific configuration value of N, then only one bit 1 is needed in the PDCCH detection status field to enable the terminal to obtain the number of transmission opportunities that require skip.

As shown in Figure 5, after the terminal skips N PDCCH detection opportunities, it detects the PDCCH at the new PDCCH transmission time and detects the signaling [0] from the PDCCH detection status field of the DCI, then the terminal will perform the next transmission opportunity Continue to detect PDCCH; it needs to be pointed out that the number of bits contained in the PDCCH detection status field and its representation method are just examples. For example, the value of N can be configured by using RRC signaling to configure the set of candidates for N, but the MAC CE is not used to notify the terminal. The specific candidates index used, and then the candidates index is carried by the PDCCH detection status field of the DCI. At this time, the number of indicator bits used will increase significantly.

Embodiment 3: If the DCI is used to instruct the terminal to no longer perform PDCCH monitoring (PDCCH monitoring) and enter the sleep state (that is, the above-mentioned instructions stop PDCCH detection at least within the current DRX on cycle), what needs to be faced The scenario is generally that the data transmission is completed, and the terminal needs to sleep to save power. However, NR and its LTE TTI (such as subframe, slot or mini slot) use the PDCCH+PDSCH structure. If the PDCCH is decoded incorrectly, the terminal will continue to detect the PDCCH because it does not receive an instruction to no longer perform PDCCH monitoring. No impact on system performance. However, if the PDCCH is decoded correctly and the PDSCH is decoded incorrectly, the terminal will no longer perform subsequent PDCCH detection and cannot receive the retransmitted version of the PDSCH in error, which will cause the packet to be delayed until the next DRX cycle. Scenarios that require high latency will not be allowed. In order to ensure that the delay performance is not deteriorated, there are preferably the following two solutions.

Solution 1: The DCI that instructs the terminal to no longer perform PDCCH detection is not transmitted in the same TTI as the PDSCH, that is, a PDCCH trigger signal (PDCCH trigger) is sent to trigger the terminal to enter the sleep state.

Solution 2: The DCI instructing the terminal to no longer perform PDCCH detection and the MAC CE used to instruct the terminal to stop the inactive timer in the DRX on period (for example: the above-mentioned non-physical layer signaling) are in the same TTI (for example, the sub-message of LTE) Box NR slot) transmission.

The time for the terminal to stop PDCCH detection takes the minimum value indicated by the two signalings of DCI and MAC CE. The principle is as follows: After the terminal detects the indication of "No more PDCCH detection will be performed subsequently" carried by the DCI, it will not detect the PDCCH afterwards regardless of whether the MAC CE is decoded correctly, and the corresponding HARQ-ACK will be set to ACK regardless of whether the MAC CE is decoded correctly or not. Give back to the network side equipment. The terminal does not stop detecting the PDCCH; the network side device receives the HARQ-ACK corresponding to the MAC CE at the corresponding location. If HARQ-ACK is detected as ACK, stop re-sending MAC CE; if HARQ-ACK is not detected (that is, PDCCH decoding fails, resulting in packet loss), the network side device can be in the remaining DRX cycle If the downlink transmission is resumed in the (DRX cycle), if the PDCCH+MAC CE of the second scheme is continued to be transmitted; if a NACK is received (for example: the corresponding MAC CE and NACK are not sent at the same TTI at this time, such as the case of sending the PDCCH trigger in the first scheme, the MAC CE can Send before PDCCH trigger), then re-send the PDCCH trigger and MAC CE or the PDCCH+MAC CE in the second solution.

Among them, scheme 1 is simple, but if the PDCCH is decoded incorrectly, the terminal will not be able to go to sleep. Scheme 2 requires the cooperation of MAC CE to achieve a better trade off.

It should be noted that the DCI instructing the terminal to no longer perform PDCCH monitoring to enter the sleep state may be included in the PDCCH monitoring status field as in Embodiment 1, or may exist as an indication field alone, regardless of whether skip N PDCCH indications exist or not. Of course, if the two are used as separate domains for indication, the priority of the two domains can be set, for example: the priority of the indication domain is higher than the detection status field, or the detection status field is higher than the indication domain.
